Theoretical progress in freezing-thawing processes studies

This and a related post reports about the Master thesis by Niccolò Tubini and Stefano Tasin. It was a couple years ago that I graduate my last Master guy, and I am happy with these two graduations.
Niccolò thesis is about modelling permafrost.

I already worked on it during the Ph.D. thesis by Matteo Dall'Amico, obtaining interesting results, which were published in this 2011 paper. From it we built. Initially the idea was that the work by Matteo dall’Amico was clear enough to go directly to a full three-dimensional implementation of 3D algorithms on a unstructured grid. That was actually not the case an we had to rework all the theory. I do not want to waste its reading. So, if you want to know the story, please click here. 

The presentation Niccolò gave for his Master (Laurea) degree is here.
